This is seen at least when building x86_64 and x86_64-gnux32 libraries on
i686-linux-gnu:
> Package: libc6-amd64
> Version: 2.27-4
> Severity: important

> On i386, libc6-amd64 and libc6-x32 install more than one gigabyte each:

Looks like that is a binutils bug, I see the same problem when building
the ncurses multilib packages. Apparently this started when I upgraded
binutils from 2.30-22 to 2.30.90.20180627-1.
These libraries have a large number of null bytes in them, their
occupied space is reduced considerably in a sparse copy:
